apt-get：如何绕过按ENTER键

Question

我在CircleCI中使用apt-get时得到Press [ENTER] to continue or ctrl-c to cancel adding it。 我怎样才能自动绕过它？
我试过用-y但没效果！

Answer 1

也许你可以考虑--force-yes标志。从手册页：

--force-yes 
     Force yes; this is a dangerous option that will cause apt to continue without prompting if it is doing something potentially harmful. It should not be 
     used except in very special situations. Using force-yes can potentially destroy your system! Configuration Item: APT::Get::force-yes. 

所以......买者自负

您可以通过这些标记永久性的为好。用下面的创建/etc/apt/apt.conf.d/文件，像/etc/apt/apt.conf.d/90_no_prompt：

APT::Get::Assume-Yes "true"; 
APT::Get::force-yes "true"; 

Answer 2

此消息来自于add-apt-repository通话茎。

您可以用-y/--yes标志绕过它。见the manpage

例如像这样：

sudo add-apt-repository --yes ppa:example/repository
